How the scan works
Siteiz measures one thing: how easily AI systems, the crawlers and assistants that increasingly read the web for people, can understand your page. Here is the approach in plain terms, and what the score does and does not tell you.
We read your page twice
We fetch your page the way an AI crawler does, as plain code with no JavaScript run, and the way a person does, in a real browser that loads everything. Then we compare the two. The difference between what a visitor sees and what a machine receives is where most sites quietly lose visibility in AI search, because many AI crawlers do not run the JavaScript your site depends on.
What we look at
Every scan grades six areas that decide whether an AI system can read, trust, and act on your page:
- Visibility. How much of what people see is actually present in the code a crawler receives.
- Actionability. Whether an agent can follow your links, navigation, and calls to action, not just a human with a mouse.
- Machine facts. The structured data and metadata that tell AI systems what your page is and what it offers.
- Crawl access. Whether AI crawlers are allowed in at all, and whether anything is quietly blocking or de-indexing you.
- Efficiency. How much effort it costs a machine to read your page, since bloated pages get skipped or truncated.
- Citability. How many concrete, quotable facts your page gives an AI to cite you on.
Each area is scored, weighted by how much it matters to AI systems today, and combined into a single grade from A to F. The areas that affect visibility most carry the most weight.
Evidence, not opinion
Every result is measured from your actual page and shown with the evidence behind it, the real titles, tags, links, and facts we found, so you can see exactly why each point moved. The scoring is consistent: the same page always produces the same score. There is no AI guessing a grade, and we never invent numbers. If a page blocks our reader or gives us too little to work with, we say so and withhold the grade rather than dress up an empty result.
What the score does not claim
A scan looks at one page at one moment, not your whole site. It measures how machine-readable your page is, not whether your content is good, true, or certain to be cited. Some AI crawlers are beginning to run JavaScript, so a gap we flag is a real risk and a real cost, not a guarantee of invisibility. We are deliberate about these limits, because a tool you can trust is worth more than one that overpromises.
